To all whom; it may concern:

Be it known that l, HARRY E. CAMPBELL, a citizen of the United States,residing at New York, in the county of New York and State ofNew York,have invented a certain new and useful improvement in Window Frames andSashes, of which the following is a specification.

The invention relates to window-frames.

and sashes of the type shown, for example, in U. S. Letters Patent No.1,273,453, granted to me July-23, 1918, and consists in the,

construction of the window-frame whereby the sashes may be easilyremoved therefrom for packing for transportation, or for repair orreplacement. The frame and sashes, as here shown, may be of wood or woodcov ered with sheet metal. The lateral extension plates on the sasheswhich enter the hollow jambs are here shown of metal and cooperate withfixed. metal walls or parti tions within said jambs.

In the accompanying draWing- Fig. 1 is a transverse horizontal sectionof the sashes and frame. Fig. 2 is a vertical sectionon the line 2,2.,ofFig. 1. Fig. 3 is an elevation of a portion of the middle section11,-sh0wing the joint between the parts of said section. t

Similarnumbers of reference indicate like parts.

3 and 4 are hollow jambs ofwood; As these jambs are alike, a descriptionof one applies to both. The front wall 5, the rear wall-6 and the outerside wall 7 are of'planking framed together. The inner wall is composedof four vertical sections, namely, an inner section '8 secured to rearwall 6 by screw 9, an outer section 10 which is rabbeted to receive theend of the front wall 5 and which protrudes outwardly beyondsaid frontwall, and two middle sections 11 and 12. The middle section 11 iscarried by a fixed metal wall 13 within the jamb. Said Wall 13 issecured between the front wall 5 and outer section 10 by the screw 14which unites said wall and section and passes through said fixed wall13. The middle section 11 is secured to said fixed wall 13 bycountersunk screws 15 and is made in two parts 16,17 disposed one abovethe other, as shown in Fig. 3, the joint 18 between them beingpreferably diagonal. The middle section 12 is secured by screws 19 tothe middle 1". section 11 and has its inner surface flush with theadjacent inner snrtaces of sections wit, an inner section,

8 and 10. Vertical gaps are left between the edges of section 12 and theadjacent edges of sections 8 and 10, through which pass metal extensionplates 20 and 21 which are secured on the verticalside rails of thesliding sashes 22, 23. These extension plates at their free edges moveover the vertical surfaces of the fixed walls' 13 when the sashes areraised or lowered. In Fig. 1, 23 is the upper and 22 the lower slidingsash, each carrying, as usual, a glass pane 24.

To remove the lower sash 22, I simply re.- move the screws 9, and sorelease the jamb wall sectlons 8. The sash is then moved in wardl intothe room. To cause its extension p ates 20 to pass the rear jamb walls6, t is alsomoved laterally in its own plane into first one hollow jamband then into the .other, so that the extension plate first on one sideof the sash and then on the other successively clear said walls.

-To remove the upper sash 23 (the lower sash having been removed) themiddle section 12 and the upper portion 16 of section 11 are taken out,when said sash can be moved inwardly into the room and caused to clearthe rear jamb walls 6 in the same way as already set forth in connectionwith lower sash 22. I claim:

1. In combination, two sliding sashes having lateral extension plates ontheir side rails,'a'frame havin hollow jambs, each jamb comprising a xedwall, wherewith said extension plates cooperate, and an inner wallformed in four removable sections, to

two middle sections, one of said middle sections being secured to saidfixed wall and the other of said middle sections being secured to saidfirst-named middle section;

there being gaps for'the reception of said extension plates between theedges of said last-named middle section and the edges &of the inner andouter sections adjacent thereto.

2. The combination of claim 1, further including said o ne middlesection made in separate y removable parts disposed one above the other.i

In testimony whereof I have afiixed my signature in presence of twowitnesses.
